| titleOfInvention | Enzyme unhairing method for protecting skin grain surface by carrying out calcium salt mineralization coating on skin surface |
| abstract | The invention discloses a method for protecting grain surfaces of raw hide by carrying out mineralization coating on the surface of the hide by using sedimentary calcium salt before animal hide enzyme unhairing, and relates to the field of leather production. The invention is characterized in that the sedimentary calcium salt is mineralized to protect the surface of animal skin grains, so that the calcium salt is deposited and coated on the surface of the raw skin, and the collagen is endowed with stronger enzyme resistance, and then enzymatic depilation is carried out. The method can effectively protect the grain surface layer collagen of the animal skin from being excessively acted by protease in the enzyme unhairing process, avoid the grain surface damage conditions such as loose surface, rotten surface and the like, does not influence the subsequent working section, and effectively improves the leather quality. The method has wide applicability, and is suitable for production of various leathers using animal skins as raw materials. |
